Nike marked the 25th anniversary of its iconic Air Max series with the sleek-designed Air Max+ 2012. The shoe is geared toward runners with a stride that is neutral to underpronated C one that rolls slightly outward upon heelstrike. 1. A double-layer mesh tongue adds ventilation. 2. The molded heel and collar lend optimal fit and reduce heel slip. 3. Reflective elements add visibility in low light.
